DISCONTINUED - The recommended replacement products are Mobilmet 402, 404 and 416.

Mobilmet Upsilon, Mobilmet Omicron, and Mobilmet Nu are high performance mineral-oil-type, non-staining cutting oils. They contain a balanced selection of additives that maximises performance. They meet the anti-weld and lubricity requirements of moderate machining operations on most alloys. These Mobilmet cutting oils do not stain either ferrous or nonferrous metals during cutting operations and, likewise, will not stain after machining. The non-staining nature of these oils permits their use where complementary oils are required for the splash, hydraulic, or spindle lubrication systems of metalworking machines, or where bronze or white metal is used in machine components such as gibs or ways that are exposed to the cutting fluid. The Mobilmet oils will provide good wear protection for such components, will not corrode the bronze or white metal parts, and will protect ferrous metals against rust. If these oils leak into the more active cutting oils, they will not seriously affect their cutting efficiency. In machines where the cutting oil leaks into the lubricant reservoir, the Mobilmet oils are ideal because they perform satisfactorily as lubricants.

Mobilmet Upsilon oil is a light-coloured, low-odor cutting oil. It is intended primarily for high-speed, deep-hole drilling and boring of all nonferrous metals. It also is recommended for the general machining of free-machining alloys, magnesium and free-machining brass, bronze, and phosphor bronze as well as high-speed, light-feed machining of screw stock steels. In addition, it can be used as a lubricating oil for certain high-speed spindles.

Mobilmet Omicron oil is primarily a dual- or tri-purpose cutting oil for automatic screw machine shops. It may be used as a cutting oil and/or a lubricating oil. It offers high lubricity and maximum cooling on hard, clean-cutting metals. This makes it especially suitable for high surface speed machining of screw stocks, aluminum, and brass. It also can be used for the general machining of nickel-tin-bronze alloys and the free-machining of steels, as well as for severe cutting operations of difficult-to-machine non-ferrous alloys, including silicon-copper, silicon-bronze, and copper-nickel. Such multipurpose applications minimise contamination caused by leakage from the lubricating system into cutting fluid reservoirs. Its outstanding lubricating qualities provide cool-running spindles and long clutch life. Mobilmet Omicron provides superior machining and lubricating performance plus the added benefit of the virtual elimination of oil mist in high-speed machine tools. This relatively light-coloured, transparent, low-odor oil has excellent oxidation stability at higher temperatures and outstanding lubricating properties under heavy loads and high speeds. It has excellent resistance to foaming, even with excessive splashing, so that superior performance is provided in the machine tool lubrication system. It will provide adequate film strength in hot-running machine tool bearings under load.
Mobilmet Nu is a heavy-duty, medium-viscosity, dual- or tri-purpose cutting oil. It offers superior cutting performance on free-machining stocks as well as tough metals, even in severe machining operations. It is an anti-mist oil and will not stain nonferrous metals. It is recommended for all kinds of grinding operations, including heavy-duty grinding of stainless steels and high-alloy steels. Mobilmet Nu reduces wheel loading, extends wheel life, improves finishes, and lowers operating temperatures. Mobilmet Nu provides excellent lubrication protection of machine tool system components under conditions of heavy loads and high speeds. Its multipurpose capability eliminates contamination caused by leakage between the lubricating oil and cutting fluid reservoirs.

The Mobilmet brand of cutting fluids has gained a well-deserved reputation for innovation and outstanding performance over the years. Mobilmet Upsilon, Omicron and Nu are an important member of this family with their effective non-corrosive additive and low-misting technology. This balanced formulation approach, developed by our formulation technologists in conjunction with key customers, yields superb performance in a wide range of machining applications, while providing good complementary oil capability.
